Custom bikes in batch sizes of one

ideas2cycles is an interesting initiative that aims to develop new bike concepts and quickly bring them to market. This idea is driven not by commercial interest, but rather the energy of a young generation: "We want to develop the craziest bikes and immediately implement our creations with the help of state-of-the-art production methods," says Kim-Niklas Antin, founder of the organisation and self-confessed bike enthusiast. "We do not want to just discuss forever; we want to turn our ideas into reality and build our own cool bikes."

There are two reasons why projects such as this one can be implemented: In the first place Antin is a graduate engineer who has required know-how, and secondly he knows about the digital production methods which allow for the cost-effective implementation of putting creative ideas into practice. In this context, Antin bases the concept of the bike frame on a simple but ingenious design, and combines the various frame tubes with exactly calculated sleeves. An magnesium alloy is used for the precision casting parts to save on weight.

"We have tried a variety of methods for building bike frames according to customer specifications in single batch sizes. The 3D printing technology turned out to be the simplest and most cost-efficient method," says Antin. The clever guy from Finland e-mails the CAD data for the sleeves to the voxeljet service centre. Here, a 3D printer quickly prepares the plastic models for subsequent precision casting in a fully automated process without the use of tools. The plastic molds are as precise and true-to-detail as prescribed by the requirements.

Kim-Niklas Antin already envisions the bike production of tomorrow: "The customer will select his favourite frame from a set of basic types, which is then customised to his requirements in CAD and subsequently printed using the 3D printing method – and that´s that."
